Abstract

Provided is a method for manufacturing a phase difference film having at least two optical anisotropic layers different from each other. In the method, a base material layer composed of a positive birefringent polymer is drawn, a negative birefringent polymer solution is applied and dried on the base material layer to form a negative birefringent layer, then, a laminated body of the base material layer and the negative birefringent layer is drawn in a direction orthogonally intersecting with the drawing direction of the base material layer.
